 with OCR getting better and better captchas soon wont be able to provide
 enough protection against bots fetching bridges anymore. but even if it
 was safe enough a censor could still hire a cheap worker to type in
 captchas all day long.

 if you let a neural network group people by typing cadence and only supply
 a group with a subset of the bridges then a single person/bot will never
 be able to pull the whole database.
